Abstract:
A semiconductor package includes a semiconductor die comprising a control transistor and a sync transistor, an integrated output inductor comprising a winding 1 around a core, and coupled to the semiconductor die. The winding comprises a plurality of conductive clips situated above a printed circuit board (PCB) and connected to a plurality of conductive segments in the PCB. The control transistor and the sync transistor are configured as a half-bridge. The integrated output inductor is coupled to a switched node of the half-bridge. At least one of the plurality of conductive clips includes a partially etched portion and a non-etched portion. The semiconductor die is attached to the integrated output inductor by a die attach material. The semiconductor die and the integrated output inductor are encapsulated in a molding compound.
